Estimating Hysteresis Effects
In this paper, we identify demand shocks that can have a permanent effect on output through hysteresis effects. We call these shocks permanent demand shocks. They are found to be quantitatively important in the United States, in particular when the sample includes the Great Recession. Recessions driven by permanent demand shocks lead to a permanent decline in employment and investment, although output per worker is largely unaffected. We find strong evidence that hysteresis transmits through a rise in long-term unemployment and a decline in labor force participation and disproportionately ...

The Slope of the Phillips Curve
We review recent developments in the estimation and identification of the Phillips curve and its slope. We have three main objectives. First, we describe the econometric challenges faced by traditional approaches of estimating the Phillips curve, explain how new approaches address those challenges, and assess which limitations still remain. Second, we review the findings of those new approaches and examine the evidence regarding a potential flattening of the Phillipscurve in the pre-pandemic period. Third, we provide an account of inflation dynamics in the post-pandemic period with a ...

The Optimal Inflation Rate with Discount Factor Heterogeneity
This paper shows that deviations from long-run price stability are optimal in the presence of price stickiness whenever profit and utility flows are discounted at a different rate. In that case, a monetary authority acting under commitment will choose a path for the inflation rate that ends with a non-zero value. Such a property is relevant in a wide range of macroeconomic environments. I first illustrate this by studying optimal monetary policy in a New Keynesian model with a perpetual youth structure. In this setting, profit flows are discounted more heavily than utility flows and the ...
